MOLDING-MACHINE.

Specification of Letters Patent.

Patented Feb.29,1916.

Application filed December 11, 1913. Serial No. 805,884.

To all whom it may concern Be it known that we, JOHN J. CRnEDoN and JOHN T. MILES, both citizens of the United States, and residents of Moline, in the county of Rock Island and State of Illinois, have invented certain new and useful Improvements in Molding-Machines, of which the following is a specification.

This invention relates to molding machines of the squeezer type which are designed to effect a compression of the flask containing the sand and pattern.

The chief object of the invention is to provide a simple, strong, convenient and easily manipulated machine, and one where- -in the presser-head can be readily swung away from above the molding bench or other support of the flask to facilitate the application and removal of the latter.

Another object of the invention is to provide a construction that will facilitate adjustment for wear of the hinge supports of the presser-head.

Still another object is to provide a construction in which the extent of throw of the operating arm or lever can be readily adjusted so as to adjust the stroke of the ram according to the depths of the molding flasks.

Other objects and advantages of the invention will be apparent from the following description taken in connection with the accompanying drawing forming a part of this specification, in which- Figure 1 is a perspective elevation, partially in vertical section of the complete device. Fig. 2 is a detail perspective elevation, partially in section, of the presserhead which carries the ram. Fig. 8 is a perspective elevation of the ram detached from the Presser-head. Fig. 4 is a detail elevation of the shaft which is journaled in the presser-head and operates the ram. Fig. 5 is a cross-sectional detail showing one of the clutch members pinned to the operating shaft.

Referring to the drawing, 5 designates an upright beam or post on which the apparatus may conveniently be mounted.

6 is a molding bench strongly mounted on the post 5 by bolts 7 and constituting the support on which the flask rests during the squeezing operation. Similarly secured to the same side of the post 5 a suitable distance above the bench 6 by means of bolts 8 is a base-plate 9 on the outer face of which are cast a pair of integral bearing bosses or brackets 10, which are vertically apertured to receive upper and lower hearing pintles 11 and 12, respectively. The lower and upper ends of the pintles 11 and 12, respectively, are tapered as shown at 11 and 12; and the pintles are adjustably secured in operative position by set screws 18 and 14:, respectively.

The resser-head consists, as here shown, of an integral castin comprising a vertical body member 15, a pair of laterally extending upper and lower arms 16 and 17, and a vertical channel-shaped casing or guide 18 for the stem of the ram. On the back of the channel-guide 18 is a boss 19 in which is journaled a horizontal shaft 20. The shaft 20 has formed thereon a pinion 21, that projects slightly through a transverse slot 22 in the back wall of the casing-guide 18, as clearly shown in Fig. 2. This pinion 21 engages arack 28 formed on the rear side of the vertical stem 24 of the ram. To the front of the casing 18 is secured bv screws 25, a removable front plate 26 constituting a guide for the front face of the plunger-stem. The upper end of the guide 18 is suitably rabbeted, as shown at 18 to receive a cap piece 27 fitted thereon and secured in place by set screws 28. To the lower end of the ram-stem 24 is secured. as by a set screw 29, the ram-head 80; it being understood that by making the ram-head separable from the stem, various sizes of heads may be employed according to the character and size of the work operated upon.

The shaft 20 is removably secured in place by means of a collar 81 (Fig. 2) secured on one end thereof by a set screw 82 and bearing against one side wall of the housing 18 and by means of a similar collar 88 keyed to the shaft by a through-bolt or pin 84 (Fig. The outer face of the collar 88 is formed with teeth 85 constituting one element of a clutch.

86 designates the operating arm or handle having a hub 87 fitted to the shaft 20; said hub having on one face teeth 88 forming the other member of the clutch cooperating with the teeth 85 of the hub 88. The end of the shaft 20 carrying the arm 86 is threaded as how f 11 W0 k11 0- e 11 1d rned the ram tr e gresb geme t 0 clut h 1 ne he (118i OI" Clg t y b 1 6 e1 fla t to e 11 head, i L b an 1 111 1 al C2 5 y Lb rile clut C 5331a 019 4 fi, 1 1 e 1 C. ll b 1 nf P fe fi 1 H of he Ir st on In In e Sill' 23 Ljfcl h Fulfi d 11' C Vice e 11 a a er-a d u 3 st 8 r 1 1111 m an hen e a scr eii/ 1 H1313 2%; b k; screw Ca 2 un 4 H d clani g of d i t e 3 thw end he p file 1 8 11131 1 lcket Idle lo bv t l per dlstanc e f ay 43 i al b wj lougl f, 16 ppe 611,1 pres n t of ne t of om t 55 bber lower 11d 4' 6 Over g n L the gas, el Oard'llh 0h ll r0 celssifie d r I X/ h it 3 5 0 I, 1 EC 11 181 1 01 th t 011 ar scr 11' p gs U S g 10];- 111 ad 11] n 1 I fela' b et -11 1st 1 e V c tb T116125 4gp I d no g eap shrew g g h sto lug Pesser-bead 1' ap ii the Cle a to 1 l 53 I Hi 1 13 2 m?

In a molding machine, the combination having tapered inner ends which engage of'a relatively stationary bracket provided so correspondingly tapered sockets in the with vertically separated, bearing lugs, a presser-head constitutes an important feapair of hinged pintles slidably mountedin mm of our invention, since it effects an aueach ofsaid lugs and-having its end toward tomatic centering of the presser-head on the j the other lug tapered, apresser headhaving lower pintle, and, further, enables the Wear tapered sockets receiving the tape-redends 85 occurring between the pintles and their ofthe pintles, a member projecting laterally bearing sockets to be radially taken up by a across the outer end of one of the pintles,
